Beat this a few months ago but just realized I didn't leave a review. Any of these sections would already be tricky on its own, but putting them all in a row like this makes for an evil level. It's hard to know where to look to save the last few steps, I had to look over each section many times before finding all the ideas.
My ranking of the sections from hardest to easiest: 5, 3, 2, 4, 1
Genius cut. I had thought about the idea earlier but couldn't get it to work the right way. Taking a break for a day definitely helps to spot these things.
Docking a half star because the level design could be cleaner, but great level overall.
